7 Backup Tractor Parts to Always Have Available

We want to help you understand what backup tractor parts you need to always have.

And as a quick aside --- we are here to help you purchase a new tractor, parts and implements when the time is right.

Let’s get started.

Preventative Maintenance

Preventative maintenance is an important part of owning and operating your tractor.

If you want it to run as strong as the day you bought it --- you must maintain it every day and at every service milestone as recommended by your tractor manufacturer.

Equipment tends to breakdown when you need it most. You might be planting or getting ready to harvest. Then you find an issue that requires a repair.

Regardless of whether you catch the issue during your routine maintenance --- or out in the field --- you need a fix --- and you need it right away.

Replacement Parts

There is a long list of issues that can instantly sideline your tractor.

If you have the right replacement parts on hand --- then you can make the necessary repairs right away --- allowing you to get back to farming with little delay.

Stock up on the tractor parts that are listed in your operator’s manual

This way you have backup replacement parts if needed.

Let’s get to the list.

Fluids and Coolants

Oil and fuel are the most important fluids in your tractor.

There are also a variety of other fluids that your tractor needs to run efficiently. Checking the engine coolant, hydraulic fluid, radiator fluid, and transmission fluid — and topping off empty tanks — should be a part of your daily preventative maintenance routine.

Clean coolant helps avoid internal damage, rust, or clogs in the engine. This helps prevent much bigger engine troubles.

Many new tractors have combined systems where hydraulic, or transmission fluid is shared between the machine and an attachment. To keep both your tractor and your implements running at full power, you need full tanks of clean fluid.


Tractors do dirty work and get filthy.

A variety of filters help protect critical components from the dirt, debris, and dust that they kick up.

You’ll need an extra oil filter, air filter, hydraulic filter, and fuel filter.

Replacement Belts

Your tractor has several different belts.

These belts keep your engine running --- and other components moving.

Alternator belts, fan belts, and air compressor belts can loosen, crack, or split. The belts for your specific tractor model may not always be in inventory at your local dealer or tractor supply store.

Plan for this ahead of time. Get replacement belts --- especially as your tractor approaches the 200-hour mark.

This could prevent a long prolonged downtime.

Zerk Fittings

Greasing your tractor should be a part of your daily maintenance checklist.

Regularly grease the joints and Zerk fittings on your equipment.

Zerk fittings are all over your machine. Many are exposed to wear and tear. While small --- a damaged or missing Zerk fitting can contaminate the grease inside your machine and cause much bigger issues.

Keep a lot of spare fittings --- so you can easily replace broken ones and keep your tractor in good condition.


All tractors and agricultural equipment are becoming more powered by electrical components. And every electrical circuit on your machine is protected by a fuse.

Electrical issues aren’t always expensive fixes. Sometimes it’s simply a blown fuse.

Your tractor’s fuses are color-coded and have the ampere rating clearly marked to ensure proper replacement.

Pick up extras.


Despite the best efforts of all the filters --- oil still gets dirty and can gunk up your tractor or even cause it to stall out.

Engine oil and hydraulic oil are regular maintenance items --- so it’s important to have plenty.

On some sub-compact tractors, the hydraulic filter is low to the ground and subject to damage from any rough terrain. If a stick or something else breaks your filter, you can lose your hydraulic oil quickly. Therefore it is important to have extra gallons available.


Having a full fuel supply might seem obvious --- but it’s easy to overlook.

If you don’t keep an eye on your fuel levels, you can waste a lot of time filling up or running out.

You also need to ensure that your fuel is clean. Diesel fuel conditioner is a fuel additive that improves the fuel quality and maintains peak engine efficiency.

Light Bulbs

Burnt out bulbs must be replaced immediately.

While you can ignore a slightly dimmer room in your home for weeks --- tractor light bulbs are there for safety — yours and those around you.

Take stock of the specific light bulbs you need for your headlamps, taillights, and warning lights.

Keep extras in your shed, garage, or even in the cab of larger utility tractors --- so that you can quickly swap out a burnt bulb and keep all the lights on.
